Can a droid (a machine) predict whether Tatooine (a circumbinary planet) is dynamically stable or not? Turns out yes! New research from the Cool Worlds team was recently published where undergrad Chris Lam wrote his first lead-author paper on exactly this. Unfortunately Chris couldn't make it to New York from his new job down in DC so Prof Kipping is taking the reigns today and explains why three-body systems are so tricky and how a neural network can save the day.
